We do the same as jrgwdenner. We only empty the fridge and tun it off when we winterize the camper other wise it is on all the time as we can connect at the house. Also runs on propane when on the road. doing this for many, many years with no problem.Oh about gas fumes..they are heaver than air they fall down the side of the truck and if you fuel properly no fumes can escape. They are very dangerous of course.The concern about smokeing when refueling is that some knuckle head will throw the cig on the ground..WHERE THE FUMES CAN GO.
